TO ALL WHOM IT MAY CONCERN:

Be it known that I, L. SAVAGE,I of Ashtabula, in the county of Ashtabula, and State of Ohio, `have invented `a. new and useful Improvement in Railroad Freight-Cars; and I do hereby declare that thefollowing is a full, cle'ar, and exact description thereof, whichwill enable those skilled in the art to make and use the same, refer ence-being had to the accompanyingdrawings,l forming part of this speciiication, in which v Figurel is a detailnsectional view of a railroad-car illustrating my invention, teken through `the line xw,ig.2. e .Y Y'

\ Figure 2 is a detail sectional view of the same, taken' through the liney y, fig. l'.

Similar lettersp'f referenceindicate corresponding parts.

Myf invention has for its object to so improve the construction of freight-.cars that the train need not bc long detained in 'loading and unloading, that thenecessity nf side tracksv and switches may be greatly lessened, and that the road can do a much greater amount of freightring business -with the same amount of rolling-stock than it can do when the cars-are constructed'inthe ordinary manner; :ind-'it consists principally in .constructing the cars in tivo parts, asv hereinafter more fully described.

. A is the rolling part of the ear. B represents the body or freight-receptacle of the car, which is made separate, and entirely distinct from the rolling part A', butin such a way as to fit upon said part` A, as shown irfig-s. 1 and 2.- When loading or unloading freight, the part B is removed from the part A upon ti'estles C, or upon a movable or stationary platform. The friction between the part B ofthe car, andthe part A and trestles or platform C, maybe diminished in various ways, as, for example, byattaching friction-wheels or rollers either to the part B, said rollers rollingupon the part A and trestles or platform C, or by attaching friction-wheels or rollers to the part A andtrc'stles or plattform C, upon which the partvB rolls in being moved upon or from the said part A; or, if desired, metallic grooves or channels D may be letr into and vsecured t0 the part A, part- B, and trestles or platform C, and the friction be relieved by ballsE, of'nny suitable materialfplaced in said grooves, ets shown in the drawings. The t`rcstles or platforms C may be made removable, or permanent fixtures,

according as the amount of freighting vor the number of cars to be loaded or unloaded at the same time may render advisable or necessary. i

I claim as new, andvdesire t o secure by Letters Patent- 1. The construction and arrangement of freigl1.t-cars iny two parts, the upper part or freight-receptacle, B,

being made Separate and 'removable from the .lower or runniirg part, A,substantially as herein shown and described, and for the purpose set forth.

` 2. Theeombination of. the metallic grooves orchannels'l) and friction-wheels E, with either or both the parte A and B of the'car, and with the trestles or platform C, for the purpose of diminishing the friction in moving thesaid part B, substantially a-s herein Vshown and described.
